How Often Should You Repaint Your House Exterior?

There’s no single number, but there is a useful rule of thumb and a set of signs that beat any calendar. Repainting on time protects the wood and siding underneath; waiting too long turns a paint job into a repair job.

Typical intervals by surface

These are general ranges — Pennsylvania’s freeze-thaw cycles and a home’s sun exposure push them shorter or longer:

• Wood siding and trim: roughly every 5–8 years
• Fiber cement (e.g., HardiePlank): often 10–15 years
• Stucco: 5–10 years depending on condition and cracking
• Aluminum siding: every 5 years or so once it starts chalking

South- and west-facing walls take the most sun and usually fail first — sometimes you only need those sides done.

The signs that beat the calendar

Look for these regardless of how long it’s been:

• Fading or chalky residue when you wipe the siding
• Cracking, flaking, or peeling paint
• Bare or greying wood showing through
• Caulk that’s split or pulled away from seams and trim
• Gaps where water can get behind the siding

Why waiting costs more

Paint is the protective layer. Once it fails, water gets into the wood and siding, and you go from a repaint to replacing rotted boards and trim — far more expensive. Catching it when the paint is just starting to fade or crack keeps it a paint job.
